A Blockwall-Type Layered Bis(dithiolato)nickelate Radical Salt Exhibiting High-and Two-Dimensional Antiferromagnetic Coupling Feature
文献摘要：
The family of[M(dmit)2]-salts(dmit2-=2-thioxo-1,3-dithiole-4,5-dithiolate;M=Ni,Pd and Pt)generally show novel magnetic,elec-tric,magnetoelectric and photoelectric properties.Herein,a blockwall-type layered[Me3S][Ni(dmit)2]radical salt(1;Me3S+=trime-thylsulfonium)was prepared and characterized by microanalysis,IR spectroscopy,thermal analysis,powder and single crystal X-ray diffraction techniques.Salt 1 crystalizes in triclinic space group P-1,with two pairs of[Ni(dmit)2]-and Me3S+ions in an asymmetric unit.The anions form blockwall-type monolayer,being parallel to crystallographic(0 1 1)plane,and the cations are accommodated in the spaces of anion monolayer.Salt 1 features a two-dimensional S=1/2 antiferromagnetic(AFM)spin system with θ=-97.8(1)K and a semiconductor with σ ≈ 10-4 S·cm-1 and activation energy Ea=0.24(1)eV in 308-368 K.1 shows two-step dielectric relaxa-tions ranged from 173-373 K and 1-107 Hz for the dipole motions of two different polar cations.Most importantly,the dielectric constant of 1 reaches to～17,with high-κ nature.This study suggests the possibility of achieving high-K materials by introducing po-lar and low rotation barrier components into van der Waals crystal and high-K[Ni(d m it)2]--based electrode materials for applications in supercapacitors.
